Abstract
Prophylactic cranial radiation (PCI) has been used in the management of small-cell lung cancer given the propensity of disease relapse in the brain. Several studies have shown that PCI reduces the rate of brain metastases and improves survival. However, the use of PCI in the management of small-cell lung cancer has been controversial due to conflicting evidence of efficacy and toxicities. For example, the most effective radiation dose and fractionation regimen is not known. Also, conflicting reports on the neurotoxicity of PCI make it difficult to make definitive conclusions regarding the side-effects of treatment. As the survival of patients with SCLC improves, the controversies regarding the neurotoxic effect of PCI may become more defined. Certainly, well-designed prospective clinical trials addressing these issues are needed and are ongoing.
